Calendar will not show specific dates in grid, only events and tasks, cannot add events
attaching screen shot, only events I set up before release 45.1.1 show. No option to add new events, fields are grayed out.

Please attach the screen shot.
Sorry, I didn't realize the pic didn't attach.
I have seen similar when the installed version of Lightning is incompatible with Thunderbird. I'd uninstall Lightning and then reinstall it, whereupon it should find and install the right version.
